GEORGE H. GREGORY, OF BROOKLYN, NEW YORK.

GAS-STOVE.

SPECIFICATION forming part of Letters Patent No. 355,393, dated January4-, 1887.

Application filed February 23, 1886. Serial No. 192.965, (No model.)

I will describe in detail a gas-stove embodying my improvement, and thenpoint out the novel features in the claims.

The accompanying drawing is a perspective view of a gas-stove embodyingmy improvement, a certain portion thereof being broken away to discloseparts which would otherwise be concealed. l

' A designates a cylindrical drum, which-will advantageously be made ofsheet metal.- This drum is provided withadoor,'a, through which accessmay be had to the interior of the drum. Its bottom will preferably beflat; but it is advantageous to provide the top with a circular raisedportion, a, somewhat inward of the side wall of the drum. The top may,however, have a flush surface. As shown, there are four of suchapertures. They afford means whereby the heat within the drum may comedirectly in contact with a kettle or other cooking utensil placed uponthe top of the drum. When such apertures are not in use for thispurpose, they may be closed by suitably-formed caps or covers of.

The drum A is supported upon a erticallyextending gas-pipe, B, whichpasses centrally through the drum. Such gas-pipe may extend directlyfrom a ceiling, as shown, or it may be curved and extend from a sidewall. The drum is intended to be vertically adjustable upon the gas-pipeand secured in any desired position thereon. I have shown in the drawinga convenient means for accomplishing this adjustment, consistingof asleeve, b, surrounding the gas-pipe near the lower end of the latter,and providedwith a series of ratchet-teeth extending in the direction ofthe length thereof. Secured to the under side of the drum is a collar,b, which surrounds the gas-pipe and the said sleeve 15. A spring-latch,b", is mounted in said collar, and is adapted to be engaged with anddisengaged from the ratchet-teeth on the sleeve 12, as will be readilyseen. By this means the drum may be adjusted vertically on In the topare apertures a.

the supporting gas-pipe." Any other suitable means for adjusting andsecuring it may, however, be employed.

The gas-pipe has connected to it above the drum by suitable couplingsseveral branch pipes, 12. I have shown foursuch pipes. After leaving thepipe B the branch pipes extend downwardly into the interior of the drumin close proximity to the pipe B, and approximately parallel therewithfor a distance. Near their lower ends they are bent at approximate rightangles to such downwardly-extending portions, and their ends areprovided with upwardly-extending burners,which may be of any suitableconstruction. Preferably, one of these burners will be arrangedbeneath'each of the apertures a in the top of the drum. The branch pipes12* are each provided with a stop-cock, 12*", outside the drum, wherebygas may be turned on or off from each of the branch pipes separately.

By adjusting the drum vertically into dif ferent positions relatively tothe gas-jets, the

latter may be brought nearer to or farther from the top of the drum or akettle or other cooking utensil supported thereon, as may be desired. i

The products of combustion are preferably carried off through tubes 0.These tubes, of which there may be any desired number, extend betweenthe top and bottom of the drum, and, as shown, are open at both ends.The lower end may, however, be closed. They are arranged, as shown, nearthe wall of the drum, and their upper ends are outside of and below theraised portion a of the top of the drum.

The pipes O are perforated. Preferably such perforations will beconfined to their upper portions. The products of combustion passthrough such perforations and escape at the upper ends of the pipes.

Air is admitted to the drum, as shown, through apertures a in the bottomthereof. I prefer to arrange deflectors a above such apertures, whichwill deflect the entering air in such manner that the flames from theburners will not be subjected directly to a column of cold air. Thedeflectors a. may be secured iirposition upon the drum by meansof'springfingers a thereon engaging with the portions of the drumsurrounding the apertures.

It will be seen that by inyimprovement the branch pipes I) become highlyheated, and consequently the gas passing through them. Oombustion istherefore much more perfect than it would otherwise be.

This gasstove may advantageously be used for heating apartments as wellas forcooking.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. In a gas-stove, the combination ofa drum, a gas-pipe upon which saiddrum is supported, branch pipes provided with burners extending fromsaid gas-pipe to the interior of the drum, and mechanism, substantiallysuch as described, whereby the drum may be adjusted into differentpositions vertically relative to the burners, substantially asspecified.

2. In a gas-stove, the combination, with a drum, of gas-pipes providedwith burners arranged therein, and perforated tubes, as C, for

carrying off the products of combustion, sub- 20 stantially asspecified.

3. In a gas-stove, the combination, with a gas-pipe, of a drumvertically adjustable thereon, branch pipes extending from said gas-pipeinto the interior of the drum, and stop-cocks 25 in each of said branchpipes outside the drum, substantially as specified.
